Until now, Mixer not only was responsible for rendering audio buffers but also managed writing them to audio backend (through a FIFO) and handled various quality related parameters. All this functionality has been moved into the new AudioOutputContext class. It glues together AudioBackend (formerly called AudioDevice), global quality settings and the Mixer. The AudioOutputContext class creates a FifoWriter which calls Mixer::renderNextBuffer() and writes the output into the BufferFifo of the AudioOutputContext it belongs to. The BufferFifo is read by the according AudioBackend which belongs to the AudioOutputContext as well. The AudioOutputContext also handles resampling in case the AudioBackend wants the buffers in a different samplerate. During this rewrite the Mixer class and the according source files have been renamed from "mixer" to "Mixer". This results in small changes all over LMMS' code base.
